ok, so no other driver than fb could use 'cfag12864b_buffer'. Maybe
I'm missing something but why did you split your fb driver into
cfag12864b.c and cfag12864fb.c ?
To be clearer. And you are wrong: you can write other modules which
want to know what the LCD is showing, or use it; without worrying
about framebuffer things. They can read / write "cfag12864b_buffer" as
well as cfag12864bfb do. Why not?
The cfag12864b module is the real driver, which uses ks0108 module.
The cfag12864bfb is just the framebuffer device.
BTW, 'cfag12864b_cache' could have been static...
Right, I saw that in the meantime I was adding the mmap feature. Thanks.
